推荐答案

查看 getCreateConstraintSQL方法AbstractPlatform类，以查看如何选择外键的名称（第1088行）。

Look at the getCreateConstraintSQL method in the AbstractPlatform class to see how the name of the foreign key is chosen (line 1088).

直接来自约束名称。影响约束名称将影响外键名称。

It is taken directly from the constraint name. Influencing constraint name will influence the foreign key name.

作为解决方法，您可以删除约束并在一个原则迁移。

As a workaround you could drop the constraint and re-create it with a new name in a doctrine migration.
